Title: Improvements in or relating to fractionator vapor condensing assembly
IPC: B01D5/00
Filed: 1956-09-04
Abstract: <PICT:0804229/III/1> In a vapour-condensing assembly, for a fractionating column 1, the condenser 3 is mounted above the condensate-receiver 8, the condensate-conduit 4 dips below the surface of the liquid in the receiver and is provided with a flow-control valve 5 which is actuated by an element 6 responsive to pressure-variations in the vapour-line 2, and the vapour-space of receiver 8 is connected by a pressure-equalizing line 21 to the vapour-line 2.  The upper part of the column, the condenser and the receiver are thereby maintained at substantially the same pressure, so that low pressures may be maintained in the column without difficulty.  In normal operation, the pressure-fluctuations in lind 2 effect adjustment of the opening of valve 5, but the arrangement is such that some of the cooling surface of condenser 3 is always covered with liquid.  The liquid withdrawn from the base of receiver 8 through line 9 is pumped through line 11, and some of it is passed through line 12 to serve as reflux in the column, while the remainder is discharged as product through line 13 which is controlled by valve 14.  When the overhead vapour is totally condensed, the liquid level in receiver 8 is controlled by element 15 which actuates valve 14. When it is desired to recover part of the product in the form of vapour, valve 20 in line 17 is opened. In this case, the liquid level in receiver 8 is controlled by the rate of vapour withdrawal; element 15 being connected to valve 18 instead of valve 14.  Reference is made to the fractionation of a hydrocarbon mixture which contains ethane and hexane.

Title: Improvements in the fabrication of printed circuits
IPC: G03F7/16
Filed: 1970-06-05
Abstract: 1,260,074. Coating apparatus. SOC. INDUSTRIELLE HONEYWELL BULL. 5 June, 1970 [5 June, 1969], No. 27428/70. Heading B2L. [Also in Division H1] An installation in which boards 34 of insulating material having one or more metallic coatings are coated with photosensitive lacquer by immersion in a bath 47 and then dried comprises a dehydration chamber 29 and a drying chamber 61 disposed side by side above the coating tank 47, means for maintaining constant the level, temperature and viscosity of the coating medium in the tank and conveyors 35 (36) for lowering the board into the tank through the dehydration chamber and lifting them from the tank through the drying chamber. The boards are fed into the coating apparatus through an opening 28 and on to a sloping rail 32 from whence they are fed in seviation to holders on conveyors 35 (36). The boards are lowered in the direction of arrow FI through a dehydryating chamber 39 fed with hot air and through a second compartment 45 where they are returned to ambient conditions of temperature by the passage of dry air. At the lowermost point of the conveyor run the boards are given a slight horizontal movement perpendicular to their planes which coats metallized holes passing through the board and prevents the formation of air bubbles therein. Upward movement of the boards carries them through a drying chamber 61 provided with an infra red heater 66. The boards are finally fed from the conveyor to a rail 70 where they pass over an oven 71 fed by a blower 72 under control of a trip 75 and then over a blower 74 which returns the boards to ambient temperature. A pump filter unit draws coating medium from the liquid surface level of the tank through a viscometer 82 which controls the feed of solvent from a tank 85. Further coating medium is held in a reservoir 86. Bubbles are removed from the filtered medium in a bubble trap 87 which has a series of perforated plates 88.

Patent GB-798700-A (GB)
Title: Automatic flight control apparatus
IPC: G01S1/02
Filed: 1955-09-28
Abstract: 798,700. Automatic steering control systems. SPERRY RAND CORPORATION. Sept. 28, 1955 [Oct. 7, 1954], No. 27633/55. Class 38 (4). [Also in Group XL (c)] A system for automatically guiding an aircraft along a course defined by a ground radio transmitter is disabled automatically by erratic changes in the radio signal received when flying over the transmitter. Derivations of an aircraft from a radio-defined course selected by a unit 12, Fig. 1, are detected on the aircraft by an omni-range radio receiver 10 developing a D.C. signal which, after conversion to an A.C. signal at 16 and amplification at 18, energizes a reversible servomotor 20 to position a shaft 30 in correspondence with course deviation. A potentiometer 26 driven by the servomotor provides follow-up and a tachometer alternator 22 provides rate feedback. An A.C. course deviation signal derived from a potentiometer 32 coupled to shaft 30 is combined with a rate of course deviation signal derived from alternator 22 and the resultant applied through a condenser 60 and contacts 62, which are normally in the alternative position to that shown, to the grid-cathode circuit of a triode valve 54. A heading deviation signal from a directional gyro 44 is also applied to the grid-cathode circuit of triode 54 so that the three signals normally combine to maintain the aircraft on course by controlling the bank channel of an automatic pilot through a limiter 68 and an amplifier 70. If due to cross-wind a course deviation tends to persist, it is integrated by an integrator 74 which adjusts an inductive device 48 to shift the datum of signals from the directional gyro, thereby correcting the deviation. When flying in the vicinity of the ground radio transmitter signals are erratic and large rates of change of course deviation signal cause alternator 22 to produce a signal which when amplified at 78 and rectified at 84 is effective to operate relay 76 to the position shown so that only signals from the directional gyro control the aircraft. Integrator 74 is still effective. Condenser 60 is charged from a D.C. source under these conditions so that when normal conditions are restored a decaying negative bias is applied to triode 54 so that the control signals only become effective again gradually. A relay 102 responsive to the output of amplifier 70 and a contact 98 dependent on the position of shaft 30 prevent operation of relay 76 during manoeuvres to get the aircraft on course. In a modification the radio produced signals are rendered ineffective in the vicinity of the transmitter, without the use of a relay, by rendering conductive a biased rectifier controlling a cathode follower valve. Use of integrals or differentials of the rate of course deviation to render the radio-produced signals ineffective is referred to. Specifications 647,469 and 791,987 are referred to.

Title: Process for producing foams from compounds of cellulose
IPC: D06M15/05
Filed: 1936-10-15
Abstract: A foam is produced by generating a gas by reaction in or by diminution of pressure on a solution of a cellulose compound with the aid of both a wetting agent (foam-builder) and a peptizing agent (foam-stabilizer).  The cellulose derivative may be an alkali or water soluble cellulose ether in solution in a concentration of 4 to 10 per cent.  The gas forming the foam may be any inert gas.  The foam may occupy a volume from 25 to 300 per cent greater than that of the original solution.  The wetting agent may be a sulphonated fatty acid such as stearic, oleic, lauric, palmitic or ricinoleic acid or a sulphonic acid of mineral or tar oils or of aromatic hydrocarbons or a sulphonated fatty alcohol, or a sulphated fatty alcohol or the inorganic or amine salts of such compounds.  The peptizing agent may be a soluble soap of an alkali metal, of ammonia or of an amine, or saponin or glycyrrhizine.  The foam which may be used to coat fibrous or textile materials may include also a dyestuff, a pigment or a filler such as whiting, starch, clay, titanium dioxide, a softener, a fireproofing agent, a waterproofing agent and other finishing agents, and after application may be coagulated and/or hardened in any suitable manner.  The materials thus coated acquire a " hand " varying from soft to full or leathery depending on the expansion of the foam.  Specifications 302,115, [Class 2 (ii)], and 390,517 are referred to.
